I am a stock assessment scientists in the FRAM Population Ecology Program at the Northwest Fisheries Science Center in Seattle, WA. I conduct stock assessments for U.S. West Coast groundfish stocks (such as Big Skate in 2019) and help support the Stock Synthesis modeling framework and the r4ss package for working with it.
